-  *
 
-  * Creates a wrapper object to allow you to work with numerical values.
 
-  *
 
-  * The primary uses for the `Number` object are:
 
-  *
 
-  * If the argument cannot be converted into a number, it returns `NaN`.
 
-  *
 
-  * In a non-constructor context (i.e., without the `new` operator), `Number` can
 
-  * be used to perform a type conversion.
 
-  *
 
-  * # Using the `Number` object to assign values to numeric variables
 
-  *
 
-  * The following example uses the `Number` object's properties to assign values to
 
-  * several numeric variables:
 
-  *
 
-  *     biggestNum = Number.MAX_VALUE;
 
-  *     smallestNum = Number.MIN_VALUE;
 
-  *     infiniteNum = Number.POSITIVE_INFINITY;
 
-  *     negInfiniteNum = Number.NEGATIVE_INFINITY;
 
-  *     notANum = Number.NaN;
 
-  *
 
-  * # Using `Number` to convert a `Date` object
 
-  *
 
-  * The following example converts the `Date` object to a numerical value using
 
-  * `Number` as a function:
 
-  *
 
-  *     var d = new Date("December 17, 1995 03:24:00");
 
-  *     print(Number(d));
 
-  *
 
-  * This displays "819199440000".
 
-  *
 
-  * The following example converts the Date object to a numerical value using
 
-  * `Number` as a function:

-  * is omitted, the number of digits after the decimal point defaults to the number of digits necessary

-  * If you use the `toExponential` method for a numeric literal and the numeric literal has no exponent
 
-  * and no decimal point, leave a space before the dot that precedes the method call to prevent the dot
 
-  * from being interpreted as a decimal point.

-  * The `Number` object overrides the `toString` method of the `Object` object; it does not inherit
 
-  * `Object.toString`. For `Number` objects, the toString method returns a string representation of the
 
-  * object in the specified radix.
 
-  *
 
-  * The `toString` method parses its first argument, and attempts to return a string representation in
 
-  * the specified radix (base). For radixes above 10, the letters of the alphabet indicate numerals
